Rate Constant

Postby ashwathinair » Sat Mar 14, 2020 9:30 pm

Wasn't sure where to put this, but is there anything that can alter a reaction's rate constant (for example, temperature or pressure)? Or does the rate constant remain the same in all situations?

A rate constant is specific for the reaction at a given temperature. Change the temperature, change the rate constant.

Rate can be changed by altering temperature or activation energy (adding or removing a catalyst)

It is related in the Arrhenius equation; k=Ae^(-Ea/RT)

The rate constant of the equation can easily alter if the reaction adds catalyst or temperature is changed. With the changes made in the system, it allows the reaction to change the rate of the reaction taking place per reaction.
